RECOlL-CHECK FOR ORDNANCE.

SPECIFICATION forming part of Letters Patent N 0. 715,278, datedDecember 1992- application filed July 5, 1901. Serial No. 67,167. (Nomodel.)

To all whom it may concern.-

Be it known that I, GUSTAVE A. LonBnN, a subject of the Emperor ofGermany, and a resident of Philadelphia, Pennsylvania, have inventedcertain Improvements in Recoil- Checks for Ordnance, of whichthefollowing is a specification.

The object of my invention is to prevent to a. great extent the recoilof guns, particularly I field-guns, which cannot be properly mounted oncarriages or bases provided with means for taking up the recoil. Thisobject I attain in the following manner, reference being had to theaccompanying drawings,in Which- Figurel is aview of sufiicieut of afield-gun to illustrate my invention in its normal position. Fig. 2 is aview similar to Fig.1, showing my invention immediately after thedischarge of the shell. Fig. 3 is a plan view of Fig. 2. Fig. 4 is anend view.

A is the barrel of the cannon of the usual construction, and on eachside of the cannon are studs a a, from which are hung links B B. Bars DD are pivoted to the links at b b. The bars D carry at their outer endsa plate E, having an opening 6, somewhat larger than the bore of thecannon. The opening is in alinement with the bore of the cannon when theplate is inthenormal position. (Shown in Fig. l.) I preferably perforatethe balance of the plate with small holes ef, so as to allow a certainproportion of the gas to escape through the perforations. Secured to alug d on the rear of each barD is a spring F, the opposite end of eachspring being secured to a stud on thebarrel of the cannon. On the link Bis astop-pin b and on each barD are two lugs or projections d d whichengage with the stop-pin. The lug-d engages the stop-pin when the deviceis in its normal position, as. shown in Fig. 1, so as to prevent itmoving back out of line, and the lug cl engages the stop-pin b when thedevice is forced into the position shown in Fig. 2.

The operation is as follows: The normal position of the recoil-checkdevice is as shown in Fig. 1, in which the opening e in the plate E isdirectly in line with the bore of the cannon, so that when the cannon isdischarged the projectile will pass through the opening 6 of the platewithout touching, and the gases that escape from the mouth of the cannonimmediately after the projectile will immediately expand and coming incontact with the plate E will force it up into the position shown inFig. 2 against the pressure of the springs. Thus the plate willimmediately receive almost the entire pressure of the gases escapingfrom the muzzle of the cannon and will direct the gases laterally andwill retard the recoilof the cannon as the pressure is equalized.

The size of the plate and the number of perforations will dependmaterially upon the bore of the cannon and the size of the charge, andthe perforations in the plate will so proportioned as to prevent therecoil of the cannon as near as possible.

As soon as the pressure against the plate ceases the springs will returnthe plate and its bars to their normal position, as shown in Fig. 1, theplate thus being automatically returned ready for another discharge.

The plate can be arranged a suflicient distance from the muzzle of thecannon to prevent the gases escaping prior to the discharge of theprojectile affecting the position of the plate.

I claim as my invention- 1. The combination of the barrel of a cannon orother piece of ordnance, and a plate having a rearwardly-extending baror bars with a plurality of links held to said. bar or bars and to thebarrel of the cannon by pivots at right angles to the bore thereof, saidplate being placed in front and out of the line of the bore of thecannon, substantially as described.

'2. The combination of the barrel of a can- ,non, a plate in front andout of the .line of said barrel provided with a rearwardly-extending baror bars, links held to said bar or bars and to the barrel by pivots atright angles to the bore thereof, said plate having a perforationnormally in line with the muzzle of the cannon, through which aprojectile may pass, the links being of substantially equal lengthand-hung from the barrel at different points, substantially asdescribed.

p 3. The combination of a cannon, a plate mounted in front of the same,rearwardly-extending bars rigidly secured to the plate, links connectingsaid bars and the cannon and one or more springs tending to retain theplate out of line with the muzzle of the cannon, said parts being soarranged that the gases which follow immediately after the discharge ofthe projectile will act directly upon the plate to move it into linewith the muzzle of the can- .non, substantially as described.

.on the bars, one lug engaging the stop-pin when the plate is in itsnormal position, the other lug engaging the bar when the plate isprojected into line with the muzzle of the cannon, sdbstantially asdescribed.

5, The combination of a cannon, links pivoted thereto, a plate havingbars connected to said links, means tending to hold the plate in adefinite position, said plate normally extending across the muzzle ofthe cannon so as to be operated upon bygases escaping therefrom andbeing provided with an opening which is in line with the muzzle of thecannon when inits normal position and through which a projectile canreadily pass, the remainder of the plate having a series of perforationssubstantially as described.

(3. The combination of a cannon, a

plate having means pivotally supporting it in front of the muzzlethereof and free to move in a direction other than that in the line ofsaid cannon, said plate having means for holding it at all times atright angles to the said line of the cannon and extending across themuzzle, together with a perforation for the passage of a projectile andother perforations for the passage of gas following a discharge,substantially as described.

7. The combination of a cannon, bars pivoted to the same, a plateperforated for the passage of a projectile having fixed to itrearwardly-projecting pieces, said pieces being pivoted to said bars,said plate being moved in front of the muzzle of the cannon by theaction of the gas following the discharge of a projectile, substantiallyas described.

8. The combination of a cannon, bars pivoted to each side of the same, aplate having rearwardly-projecting pieces fixed to-its edges, saidpieces being pivoted to said bars and normally supporting the plate sothat it extends across and below the muzzle of the cannon, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
